About Nacho

I help businesses automate workflows, connect AI with their existing tools, and turn agentic AI ideas into practical visual platforms.

With over 6 years of experience as a Data Scientist at Alto Intelligence, I have worked on data analysis, process automation, dashboards, machine learning models, algorithm development, and AI-based solutions for extracting insights from large volumes of information.

Today, under the commercial name ByTheBot.com, I build AI automation systems, internal tools, and AI-powered platforms connected to real business workflows through Python, APIs, CRMs, databases, Google Sheets, WhatsApp, email systems, and dashboards. My work combines Python backends, AI integrations, databases, and AI-assisted front-end development to turn automations into usable platforms, as implemented in projects such as Euroformac. ByTheBot also includes a replicable conversational operations platform to monitor interactions, intervene when needed, manage automations, and track real-time metrics.
